Patent JP-S5565464-A (JP)
Title: Charge-coupled device
Inventor: TAKEUCHI EIICHI
IPC: H04N5/335
Filed: 1978-11-13
Abstract: PURPOSE:To obtain accurate output signals, by surrounding both sides of a carrier transfer main channel with auxiliary transfer channels and setting a fixed DC level corresponding to a dark current where incident light is shut off and light is detected. CONSTITUTION:Both sides of charge transfer main channel 6 are surrounded by auxiliary channels 10, 11. Since these are shut off from light, thermal dark current is accumulated in a potential well here, so that they are free from the effect of charges produced by incident light. Channel 10 collects charges produced and scattered by incident light in places other than an activation unit, and channel 11 collects charges produced by the incident light of main channels 7-9 and are unable to be contained in the potential well. Signal charges accumulated in photoelectric converter unit 1 are added with pulses successively and are transferred to register 3 in parallel via storage unit 2, and they are detected (4) and read as output signals. At this time, level signal 6a corresponding to the dark current from channel 6 is taken out, and section T corresponding to the dark current of the input signal is fixed at a specified DC level VR. Consequently, the effect of the dark current is removed.

Title: Image forming device
Inventor: KUSAKA KENSAKU
IPC: H04N1/29
Filed: 1986-06-17
Abstract: PURPOSE:To arrange a fan and filter closely to each other so as to miniaturize an image forming device, by providing a dust filtrating filter and a means which uniformizes the flow speed of an air current on the suction side of an exhaust fan. CONSTITUTION:An air cleaning exhaust means is constituted of a fan 15 and an air flow speed regulating member 17 and filter 16 provided on the suction side of the fan 15 and the ozone and dust of developing agents, fibers, etc., produced in this picture forming device and contained in the exhaust air are caught with the filter 16 and removed. When the regulating member 17 is not provided, the air flow speed distribution in the direction Xh-Xl of the filter becomes extremely larger on the upper half side as compared with the lower half side and the ozone removing rate is reduced. Since a turbulance flow is produced and the pressure loss is increased when the regulating member 17 whose height corresponds to the height of the upper half section of the filter 16 is provided closely to the filter 16, the speed of the air flow is uniformized over the entire cross section of the air flow and the ozone removing rate is increased even if the fan 15 and filter 16 are arranged closely to each other. Therefore, the whole body of the image forming device can be miniaturized.

Title: Thin photosensitive film device
Inventor: TAKEDA YOSHIHIKO
IPC: H04N5/335
Filed: 1990-05-30
Abstract: PURPOSE:To sufficiently lower crosstalk caused by obliquely incident light by forming a groove on a light transmitting substrate on which a photosensitive element is formed. CONSTITUTION:An obliquely incident light to a G filter 13b is reflected at a part of interface and remainder is incident to the filter. This incident light changes to the green light after the lights other than green light are absorbed within the filter and then enters a glass substrate 11. A refraction index in the visible light region of this glass substrate 11 is, for example, about 1.6. In this case, since the refraction index of epoxy filter is about 1.6 and that of air is 1.0. Therefore, the incident light travels almost straight at the interface between the filter and glass and reaches a groove 14 formed on the light transmitting substrate, is subject to total reflection at the interface between the air of groove 14 and glass and then enters a pbotosensitive element 12b for G filter without entering the other elements. Accordingly, a color sensor reduces crosstalk of light and realizes improvement of sensitivity by trapping the light.

Filed: 1982-08-12
Abstract: PURPOSE:To contrive the industrial application of a connecting flow type impeller, by intermittently detecting the rotary signal of the impeller by a microprocessor, storing the signal, and computing a current flow rate and an integrated flow rate. CONSTITUTION:The signal from a magnetic oscillating element, which is sealed in each vane of a connecting flow type impeller 2 is sent to a microprocessor unit 6 and a relay box 7. Low frequency and high frequency noises are removed by a capacitor 30 and a zero point adjusting circuit 31 and the judged signal is obtained and sent to a microprocessor 34. A pulse length and a frequency are computed from each signal at every sampling command 36 from a clock circuit 35, and the result is stored in a memory 37. Then an average frequency within a specified time is obtained and an estimated flow rate is computed. Thereafter the instrument error is corrected. Then the measured flow rate is obtained from the corrected flow rate by a weighted mean method. Since the accurate flow rate can be obtained in the low flow rate region in this way, the flow rate can be controlled in comparison with the preset flow rate.

Title: Focus detector
Inventor: UTAGAWA TAKESHI
IPC: G02B7/34
Filed: 1987-06-05
Abstract: PURPOSE:To remove the shading of light flux, to surely detect a focus and to prevent low brightness detecting capacity from being deteriorated by inserting an optical member for reducing an opening angle of detected light flux without changing the size of an aperture part of an image reforming lens into an image reforming optical system. CONSTITUTION:The optical member 101 is freely attachably/detachably arranged between a focus detecting face 107 and an image reforming lens 102 and the member 101 is provided with lens systems 101a, 101b for reducing a detected opening angle theta' from a detected opening angle theta of a pair of detected light beams 108a, 108b obtained before loading the optical member 101 without changing the size of a pair of aperture parts of the lens 102. Since the detected opening angle on the photographing lens side can be varied by attaching/detaching the optical member 101, unevenness or vignetting is not generated in a pair of detected light beams which may be generated by a variable diaphragm like an ordinary case. Since the aperture diameter of the image reforming lens is not changed by a fixed diaphragm even if the detected opening angle is reduced by loading the optical member, a low brightness lamination capable of detecting a focus is not deteriorated.
